GUMMING APPARATUS FOR RIBBON -CUTTIN G- MACHINES.

Specification of Letters Patent.

Patented May 14., 1918.

Application filed August 28, 1917. Serial No. 188,585.

To all whom it may concern:

Be it known that I, HENRY D. SCHMIDT, a subject of the Emperor ofAustria. residing at Astoria. L. 1., in the county of Queens and Stateof New York, haveinvented certain new and useful Improvements in GummingApparatus for Ribbon-Cutting Machines. of which the following is aspecification.

This invention relates in general to gumming apparatus and is directedparticularly to an apparatus of this character adapted to be used inconjunction with ribbon cutting machines or the like. In the ordinaryuse of these machines after the ribbon has been cut into strips a roughedge is left by the cutter which may easily cause the ribbon to fray orfringe. To prevent this a layer of some adhesive substance is usuallyapplied to the newly out ribbon edge.

My main object in this invention, therefore, is to provide a gummingapparatus which may readily apply the layer of adhesive substance to thenewly cut ribbon during the cutting process.

Another object'of my invention is to provide an apparatus of thischaracter having means for varying the thickness of the layer ofadhesive substance.

A further object of my invention is to provide an apparatus of thecharacter described having means for the adjustment thereof relative tothe cutting knives.

A still further object of this invention is to provide a gummingapparatus which may be easily attached to the ordinary forms of ribboncutting or like machines, readily manipulated, eflicient in itsoperation and inexpensive to manufacture.

Further objects and advantages of this invention will appear from thedetailed description and the features of novelty will be moreparticularly pointed out in the ap-' pended claims.

In the drawing formmg'a part of this specification, Figure 1 is anelevational view partly in section showing the essential parts of aribbon cutting machine with an embodiment of my novel gumming apparatusattached thereto; Fig. 2 is an elevational view of an embodiment of thegumming apparatus itself; Fig. 3 is a plan view thereof, and Fig. l isan enlarged detailed section taken along line H of Fig.2, showng themeans for adjusting the gumming apparatus relative to knives.

Referring in detail to the drawing, 10 represents a roll of ribbon 10which is inade to unwind over a roll 11 disposed in operatlve relationto a circular cutting knife 12. The out ribbon unwinds from said roll 11onto auxiliary rolls, such as 13 and 14. As is usual in the ordinaryform of ribbon cutting machines, the roll of ribbon 10 is kept compactby means of the small rollers 15 and 16 held down against the .materialbv the weight of the member U My novel gumming apparatus will now bedescribed. a As will be clear from the drawing, the embodiment of myinvention therein shown comprises a container or the circular cuttingtrough 18 which serves as a receptacle for any suitable gummingsubstance, preferably in liquid form. A bar 19 is milled out on one endto provide a recess 20 within which rotates a wheel or roller 21 mountedon a shaft 22 passing through the bar. As will be clear from Fig. 1, thecircular cutter 12 and this gumming roller 21 are in frictional contactand the rotary motion of the for mer'is imparted to the'latter. The bar19 is mounted on the stand or frame23 of the ribbon cutting machine andis so disposed relative to the gumming trough that the gumming roller 21dips thereinto. It will now be clear that as the circular cutter 12rotates, the cutting edge thereof has applied thereto the layer ofadhesive substance through contact with the gmnmed roller, and thislayer is in turn applied by the cutter to the ribbon during theoperation thereof as clearly shown in Fig.1.

To provide for varying thicknesses of adhesive substances I preferablyform the 9 bar 19 with a projection 24 adapted to hold a curved blade orevener 25 which extends through the recess 20 in the bar over the roller21 in spacedrelation thereto. A set screw 26 operates through an openingin the end 27 of the bar and is adapted to force the evener 25 which issomewhat resilient to ward the gumming roller. The thickness of thelayer of adhesive substance is thus regulated by said evener accordingto its adjustment.

To keep the apparatus in position relative to the trough and infrictional contact with the cutter, I provide preferably a counterpoise28 held on the opposite end. :29 of the bar by means of the screw 30.

It is desirable in an apparatus of the nature described herein toprovide meansfor the adjustment thereof relative to the circular cuttingknives. I, therefore, preferably form the bar 19 with a hole 31 adaptedto receive a screw 32. The material of timber about the opening 31 iscut away as at 33 to permit a sleeve 34 to he slipped thereover from oneface of the bar, the collar 35 for the sleeve being secured on the otherface in some suitable manner. A nut 38 havin at one end a removable head39 is mounte on the screw 32 and carries the sleeve 34:. By manipulationof the nut 38 the whole lar cutting knives 12. Of course, other methodsfor accomplishing this adjustment will readily occur to one skilled inthe art, and I do not limit myself to the specific constructionhereinabove described and explained.

It will thus be clear that I have provided a novel gumming apparatusreadily attached to ribbon cutting or like machines having means forvarying the thickness of the layer of gum to be applied to the cutribbon, means for adjusting the position of the gumming apparatusrelative to the cutting knives and yet withal simple in construction,effective in operation, easy to manipulate and comparat vely inexpensiveto make.

It will be understood, of course, that I do not limit myself to thespecific structure shown in the drawing, since many changes may be madein the constrpction without departin from the spirit of my invention.

Having thus described my invention, what I claim and desire to secure byLetters Patent is: e

1. In a ribbon cutting apparatus or the like, the combination with acutter, of means for applying a layer of adhesive material to thecutting edge simultaneously with the cutting operation.

2. In a ribbon cutting apparatus or the like, the combination with acutter, of means for applying a layer of adhesive material to the cutedge of the material simultaneously apparatus may be adjusted relativeto the circuwith the cutting operation whereby the said edge is gummedto prevent fraying thereof. r

3. In a ribbon cutting apparatus or the like, in combination with acutter, means cooperating with the latter for gumming the cut edge ofthe material.

4. A gumming apparatus comprising in combination with a cutter, acontainer for gumming material, and a rotary means dipp1 ng thereintoand adapted to cooperate with the cutter and apply the gummingmaterial-to the cutting edge thereof.

5. In a ribbon cutting apparatus or the like, in combination with acutter, means 00- operating with the latter for applying a layer ofadhesive material to the cutting edge thereof and means for varying thethickness of the layer of adhesive material.

6. In a ribbon cutting apparatus or the like, in combination with acutter, means co operating with the latter for applying a layer ofadhesive material to the cutting edge thereof and means for adjustingthe gum applying means relative to the cutter.

7. In a ribbon cutting apparatus or the like, in combination with acutter, means cooperating with the latter for applying a layer ofadhesive material to'the cutting edge thereof, means for varying-thethickness of said layer and means'for adjusting the position of saidgumming means relative to the cutter.

8. A ribbon cutting machine or the like comprising a roll carrying theribbon to be cut, circular cutters and circular means in frictionalcontact'with said cutters for applying a layer of adhesive substance tothe cutting edge of said cutters simultaneously with the cuttingoperation.

9. A gumming apparatus for material to be cut into'strips comprising incombination with a circular cutter, circular gumming means adapted toapply the gum to the edge of said cutter during the cutting operationand held continuously in frictional contact therewith. V

In testimony whereof I vaffix my signature in presence 0 two witnpsses.
